I had it for first pregnancy. I eat in small meals, lessen all spicy food, fried food, I will drink more plain water. When sleeping I seat/slouch/side ways. And of course I dont eat nearing to bedtime because food takes longer to digest, once I seat or lay down I get acid reflux easily. So I must have nice gap of time between meals. Also because baby's growing lesser space to move that is also part of the reason why constantly preggy mum will have acid reflux or heartburn.
